VALVE.

Specification of Letters Patent.

Patented Oct. 9, 1917'.

Application filed October 25, 1916. Serial No. 127,609.

To all whom it may concern:

Be it known that we, JAMES B. STEWARD- SON and SAMUEL S. Srnwennson,citizens of the United States, residing in North Randall township, inthe county of Thomas and State of Kansas, have invented certain new anduseful Improvements in Valves, of which the following is aspecification, reference being had to the accompanying drawings whichform a part hereof. Our invention relates to an attachment for internalcombustion engines and consists of a valve for regulating the supply ofmoisture and air to the charge mixture.

The principal object is to provide means for successfully regulating thecombination and supply of moisture and air and the operation of suchregulation by means under the immediate control of the driver.

We attain these objects by means of the mechanism hereinafter describedand illustrated in the accompanyingdrawings in which the single figureis a longitudinal sectional view of our improved valve.

The several parts are designated by on dinals to which reference is madein the following description.

Our valve comprises casing 4, flange or plate 5 by means of which thevalve is secured to inside of dash, inside-gland 6, capgland '7.attached by threaded connection to an extension of said inside-gland,stufling boxes 8 and 9, needle-stem 10, needle 11, needle-seat 12.ncedle-seat-cutott" 13, crankarm 14 secured to cutoff 13, rod 15pivotally secured to said crank-arm and connecting with the sparkcontrol lever by means of which the cutofi 13 is operated. I

A. groove 18 surrounds gland 6 and ports 19 therefrom provide entrancefor the water into chamber 20; such water being supplied from the waterjacket or other source through pipe 21. The water, the quantity beingregulated by needle 11, passes from chamber 20 through opening 22 inseat 12 to chamber 23 in cutolf 13, where it mixes with the air enteringsaid chamber through opening :24 provided therefor. A port 25 leadingfrom the chamber 23 when the cutoff 18 is in open position meets port 26through the casing where the same connects with pipe 27. This mixture ofwater and air through port 25 passes into pipe 27 by means of which itis conducted to a tube or other means of supplying the moisture or airor both combined to the intake mani-;

The

appear to be too much or too little water supplied to the charge mixturewithin the manifold such supply is regulated primarily by means of theneedle-valve and when this is properly adjusted the operator may readilycontrol the same by means of the spark control lever and cutolf asheretofore described. I

Having thus described our invention what we claim as new and desire tosecure by Letters Patent is- In combination with an internal combustionengine, a regulating valve comprising a casing, inside-gland,needle-stem passing through a chamber in the interior of said gland andin threaded adjustment connection with said gland. a stufiing-box at theinner end of said inside-gland, a cap-gland to said inside-gland, aneedle extension of said stem in relat on to a seat provided with a porttherethrough, a groove between the walls of the inside-gland and thecasing, port connection between said chamber and said groove and portconnection from said groove through the wall. of said casing, aneedle-seat cutoff in threaded ad ustment connection with said casing. achamber in the interior of said cutoff. a port through the needle-seatopening into said chamber, and an outlet port from said chamber throughthe wall of said casing.
